W and S to move the moderator E and D to move the control rods the blue dots are fuel the light grey dots are not fuel, they eventually turn to fuel. Note: in real life the non fuel does not turn to fuel the black dots and lines are the thing that absorb neutrons the dark gray lines turns fast neutrons into slow neutrons the slow neutrons can react with the fuel and the fuel will release 3 fast neutrons the fast neutrons cannot react with the fuel Note: do not expect this simulation to be realistic
i made this for the SDS
